Oracle's Siebel Systems named as a top California tax delinquent

Siebel Systems Inc. of San Mateo owes California $1,371,765 in unpaid taxes, putting the company on the state's list of top tax delinquents.

The California Board of Equalization added Siebel, now owned by Redwood City giant Oracle Corp. (NASDAQ: ORCL) to its list of the 500 biggest delinquents for the third quarter of 2012.

California put a lien on Siebel Systems property on March 7.

Brian Miller, a Board of Equalization spokesman, said the BOE can't comment specifically on why a person or business is listed, because this violates tax privacy laws.

Oracle, led by CEO Larry Ellison, didn't respond to a request for comment. It bought Siebel in late 2005 for $5.85 billion at the end of a "year of the deal" when it also bought PeopleSoft Inc. in Pleasanton.
